Show Suggested Answer

Suggested Answer: B, D, E

Junos platforms use different mechanisms to evaluate incoming traffic for CoS purposes, such as:

Behavior aggregate classifiers: These classifiers use a single field in a packet header to classify traffic into different forwarding classes and loss priorities based on predefined or user-defined values.

Fixed classifiers: These classifiers use a fixed field in a packet header to classify traffic into different forwarding classes and loss priorities based on predefined values.

Multifield classifiers: These classifiers use multiple fields in a packet header to classify traffic into different forwarding classes and loss priorities based on user-defined values and filters.

Rewrite rules and traffic shapers are not used to evaluate incoming traffic for CoS purposes, but rather to modify or shape outgoing traffic based on CoS policies.

Hmm, C seems like the clear winner here. Configuring multipath multiple-as is the only way to actually load balance the traffic across the two BGP sessions. Unless R1 and R3 are trying to pull a fast one on us, that is.

I agree, C is the best option for load balancing.

I'm feeling confident about C. The other options just don't seem to address the requirement for load balancing the route. Although, I do wonder if R1 and R3 are secretly rooting for me to pick the wrong answer...

I think the answer is A) Configure the multipath parameter under the global BGP configuration.
